[Problem] To provide a compound which can be used for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).
[Means for Resolution] It was found that an amide derivative characterized by the possession of a nitrogen-containing bicyclic hetero ring (e.g., an indole or the like), or a pharmaceutically acceptable salt thereof, has a strong antagonism for both of the 5-HT2B receptor and 5-HT7 receptor. In addition, the compound of the present invention having the antagonistic activity for both of the receptors showed a good pharmacological action in comparison with the case in which an antagonist selective for either one of the receptors was used alone. Based on the above, the compound of the present invention is useful for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).
[问题]提供一种化合物,该化合物可用于预防和/或治疗与 5-HT2B 受体和 5-HT7 受体有关的疾病,特别是用于治疗肠易激综合征(IBS)。
[解决手段]研究发现,一种以具有含氮双环杂环(如
吲哚或类似物)为特征的酰胺衍
生物或其药学上可接受的盐,对5-HT2B受体和5-HT7受体均有很强的拮抗作用。此外,与单独使用对其中一种受体具有选择性的拮抗剂相比,对两种受体都具有拮抗活性的本发明化合物显示出良好的药理作用。基于以上所述,本发明化合物可用于预防和/或治疗与 5-HT2B 受体和 5-HT7 受体有关的疾病,特别是用于治疗肠易激综合征(IBS)。
